Consequently, the inlet air duct 25 has a cross section which is no longer perfectly symmetrical, whereby the inlet air flow II is divided into different air streams or free jets I. According to the embodiments shown in FIGS.
  • the bearing section 230 is arranged in the housing 12 of the air vent 10 such that the inlet air duct 25 is subdivided downstream into an upper outlet 40 in FIG. 5A and a lower outlet 55, each having an outlet opening 15 form. It should be noted, however, that also more than two outputs 40, 55 are provided can. In particular, it is possible to provide two further outlets (not shown), which are arranged in principle like the outlets 45 and 50 described according to FIG. 1A. In this case, the dome 240 is movably supported on the support portion 230 not only in the vertical direction shown in Figs. 5A and 5B but also perpendicular thereto (or orthogonal to the paper plane).

  • the air flow I leaves the air outlet 10 in such a way that it flows as the only air jet in the direction of the focal point F and sweeps it over.
  • the number of free jets I, their respective volume flow and direction by a suitable adjustment of the adjusting means 30, thus a suitable translation of the adjusting means 30 about the translation axis S, can be adjusted.
  • the outputs 40, 45, 50 and 55 previously shown in the respective embodiments have been described as being aligned substantially parallel to each other. However, it is also advantageously possible to align one, some or all of the outputs 40, 45, 50 and 55, respectively, not parallel to one another. Thus, it is possible in a particularly advantageous manner to align some or all outputs 40, 45, 50 and 55 to each other, so that a movement of the or the free jets I is supported each other. This is all the more true if the passage openings 90, 95, 100, 105, the outlet channels 150, 155, 160, 165 or the channels 175, 180, 185, 190 are also aligned with each other at their respective ends.
